Definitions
- the invention relates to a brass alloy for use in the manufacture of semi-finished products intended for machining, consisting of copper, zinc and additional alloy components.
- Corresponding brass alloys are often produced as semi-finished products in strip or wire form and subsequently processed into finished products. The further processing takes place frequently by application of cutting operations.
- lead When machining brass, it has proven advantageous in the past to add lead to the alloy in an amount of up to four percent by weight.
- the lead has a positive effect as a chipbreaker, extends tool life and reduces the tensile forces. Important material parameters such as strength and corrosion resistance are not adversely affected by an addition of lead.
- a brass alloy of the aforementioned type has become known, which contains in a variant except copper and zinc components of iron, nickel and tin and less than 0.1 weight percent lead, but additionally has a proportion of 0.49 weight percent bismuth.
- a brass alloy has become known which has no content of lead, but except copper, zinc, iron and tin a Contains 2.3 wt% bismuth.
- Object of the present invention is to define a lead-free brass alloy of the aforementioned type such that it achieves good machinability, sufficient mechanical properties and the lowest possible wear on the cutting tools used and that at the same time the lowest possible content of expensive and / or having environmentally harmful alloying elements.
- the invention is further based on the object to achieve specific properties by the targeted combination of non-polluting alloying elements and on the manufacturing process.
- the content of lead is at most 0.1 percent by weight, that the proportion of zinc 40.5 to 46 weight percent and the proportion of copper is at most 59 percent by weight and that the alloy mixed crystal having proportions of both an alpha microstructure and a beta microstructure, wherein the weight fraction of the beta microstructure is at least 30% and at most 70%, and that the proportion of each of the additional alloying components is selected from the group consisting of iron, nickel, tin, manganese and silicon is at most 1.0 weight percent and the sum of the proportions of all of these additional alloy components is at least 0.5 weight percent.
- a particularly important feature for solving the problem underlying the invention is further that the proportion of elements that are not copper, zinc, iron, nickel, tin, manganese or silicon is less than 0.2 weight percent.
- each of the mentioned alloying elements in a higher concentration in each case, without thereby increasing the total amount of alloying elements (except copper and zinc).
- the precipitations contained in the microstructure which are also found in the soft alpha microstructure, support the chipping behavior positively.
- the alpha microstructure of the mixed crystal forms a cubic surface-centered spatial structure.
- the beta-mixed crystal forms a cubic body-centered structure.
- the proportion of the beta structure is at least 50%. This is particularly supported by the fact that a zinc content of about 42 percent by weight is present.
- the elements iron and nickel have a regulative influence on the grain growth of the alpha and beta phase, with nickel additionally promoting the stabilization of the alpha structure. Too high levels lead to embrittlement of the alloy.
- the elements tin, silicon, manganese and iron stabilize and increase the proportion of the beta phase.
- phosphorus may be provided.
- a maximum proportion of phosphorus in the range of 0.1% by weight is intended.
- the content of copper is 54 to 59.0% by weight.
- the proportion of zinc is 40 to 46 weight percent.
- a first additional alloying component is defined by the proportion of iron being from 0.1 to 0.5 percent by weight. Iron is used to control the grain size of the alpha and beta phases. Contents less than 0.1% do not have a sufficient effect. Shares greater than 0.5% would lead to very large iron precipitates, which have a negative effect on the mechanical properties of the alloy. In particular, it is contemplated that the proportion of iron is 0.2 to 0.3 weight percent.
- a second additional alloying component is defined by the proportion of nickel being from 0.1 to 0.5 percent by weight. Nickel stabilizes the alpha phase.
- the proportion of nickel is 0.2 to 0.3 weight percent.
- An additional optional alloying component is defined by the proportion of silicon being 0.01 to 0.20 percent by weight. Silicon stabilizes the beta phase and together with other elements forms fine precipitates, which have a positive effect on the cutting behavior and are responsible for grain refining. In particular, it is contemplated that the proportion of silicon is 0.03-0.08% by weight.
- An additional optional alloying component is defined by the proportion of manganese being 0.01 to 0.20 percent by weight.
- Manganese stabilizes the beta phase and together with other elements forms fine precipitates, which have a positive effect on the cutting behavior and are responsible for grain refining.
- the proportion of manganese is 0.03 to 0.08 weight percent.
- a third additional alloying component is defined by the proportion of tin being from 0.1 to 0.5 percent by weight.
- the proportion of tin is 0.2 to 0.3 weight percent.
- Phosphor leads to an improved corrosion resistance of the alloy, in particular P also counteracts dezincification.
- a preferred embodiment of the alloy preferably has the following percentages by weight with respect to its composition. Copper in the range of 54% to 59.5%, zinc in the range of 36% to 40.5%, iron in the range of 0.1% to 0.5%, nickel in the range of 0.1% to 0.5 %, Silicon in the range of 0.01% to 0.2%, manganese in the range of 0.01% to 0.2% and tin in the range of 0.1% to 0.5% and lead with a maximum of 0.1%.
- the lead content of the alloy is, also due to the use of scrap in the production of such alloys, max. 0.1%.
- the proportions of copper and / or zinc are optionally reduced.
- the proportion of copper is 57.0% to 57.5%, the proportion of zinc 41.9 to 42.5, the proportion of nickel 0.2% to 0.3%, the proportion of iron 0.2% to 0.3%, the proportion of silicon 0.03% to 0.08%, the proportion of manganese 0.03% to 0.08% and the proportion of tin 0.2% to 0.3 % and lead content less than 0.1%.
- the sum of the weight proportions of all other possible components is not more than 0.2%.
- compositions it is basically possible to add only some of the listed elements to the alloy. According to a very particularly preferred embodiment, however, it is envisaged to add all the above-listed elements with a weight proportion within the respectively defined intervals in combination with one another to the alloy.
- the lead content is in an interval of 0.01% to 0.1%. Due to the relationship between the alpha-mixed crystal and the beta-mixed crystal according to the invention, the desired material properties can be achieved even with reduced lead contents.
- the alpha-mixed crystal leads to a relatively good deformability of the alloy and gives this tough properties.
- the beta-mixed crystal is, however, relatively poorly deformable and brittle. These properties are desirable for good machinability.
- the relationship of the alpha and beta fractions according to the invention thus gives the alloy sufficient toughness to aid ductility and brittleness to aid machinability.
- a preferred production process may be carried out by first performing extrusion molding in a temperature range of 600 to 750 ° C. This produces a microstructure which has a proportion of the beta mixed crystal of about 50 percent by weight.
- an intermediate annealing at a temperature of about 500 to 600 ° C. is carried out after a first forming step.
- the intermediate annealing leads to a recrystallization and thus to a Kornneu Struktur. As a result, a fine-grained microstructure is supported.
- the brass alloy of copper and zinc with a lead content of 0.01 to 0.1 percent and with at least one further alloying component.
- This further alloying component influences the microstructure of the mixed crystal in order to achieve the respective desired material properties depending on the application.
- This embodiment leads to a particularly high proportion of beta-mixed crystals between 55 and 70% beta-portion, which causes a particularly short-breaking chip.
- Another preferred embodiment is provided in terms of weight percent by the following alloy.
- the brass alloy according to the invention serves to produce so-called semi-finished products which are subjected to at least one further processing step.
- the semi-finished products are typically produced by a casting process. Typical embodiments of such semi-finished products are wires, profiles and / or rods.
- the further processing step comprises at least one machining operation.
- the further processing step may comprise a combination of shaping and machining.
- the shaping can be carried out both at room temperature and at an elevated temperature. At the elevated temperatures, a warm half-temperature can reach up to about 450 ° Celsius and a hot working temperature be distinguished in a range of 600 ° Celsius to 850 ° Celsius.
